.ALL WHQM I'l MAY lCONCERN: l v Be it known that LJ. M. SPITL'ER, ofClinton, in the county of Douglas, and Stateof Kansas, have `invented a.new and useful Improvement in lVagon-Jnck; andy I do hereby declare thatthe following isa full,

clean-land expect description thereof', which will enable others skilledin the a-rt to make anduse the same, vreference being had to theaccompanyingdrawings, forming part of this specification, in which-Figure 1 is a loi'igitudinal-,section of my improved wagon-jack.

Figure 2 is a; similar section taken at right angles to g. l. i

Similar letters of reference indicate like parts.

This invention relates to an improved wagon-jack; and consists ofa'hollow block or standard enclosing longitudinally a movableextension-bnr, which may be raised more orless for lifting thevaxle ofa. wagon or other vehicle, by mea-ns of ratchetteethou its sides whichengage an oscillating handle, ns hereinafter-more particularlydescribed.

A is a long,'square supporting box or hollow standard enclosing nlifting-balB, having ratchet-teeth a a on two opposite sides pointingdown-wards. Thelfting-bar B projects frointhe upper end' of the standardA,

and is sheathed'in it when vnot extended for lifting an axle. Theforkedends b b of la handle, C, nre inserted in one side ofthe standard A. atthe upper end7 and urepivoted-in it centrally-onopposite sides 'of theliftingb-ztr B. The forks bb have iron-rod catch-loops c c suspended tothem on Aeach side of -the lifting-bar B, in such manner that the loopsshall catch alternately in the ratchet-teeth a loon the sides of the'bar as the handle C is raised or depressed. Long lever-springs d nreplaced on the inside of the standard A, to beur upon the catch-loops ceand force theminto vthe ratchet-teeth for the purpose of raising thelftingbar B when the handle C is worked up and down like a pump-handle.These springs are pivoted-nt e e, and onthe end of their short arms nreconnected by links g g with a. slide-piece, D, in such manner that whentheslide-piece is' depressed the springs d d will bear upon' the .loopsc a and mnke them catch in the ratchet-teeth a a toraise the liftingbarB by working the handle C; .and when the slide-piece Dis elevated bymeans of a side lever, h', the springs d d will be opened to disengagethe loops c c from the`1'ntchet-teeth, allowing the lifting-ber C to bepushed back into the standardfA. On the other end of` therslide D isconnected a spring-catch, c, that locks into the lower end of thelifting-bar C when it is fully'elevatetf, to hold itin the standard.

l The operation, by setting the standard A under an a'xle in ein uprightposition, and elevating the liftingbar B as high as desired toraise'tlie wheel, is very simple, easy, and effective, and thelifting-bar will keep its place firmly i Having thus described myinvention, .I claim -es new, und desire to secure by Letters Potent- Thelifting-bar B provided with ratchet-teeth a a, in combination with theforked handle C and catch-loops c c, the springs d d, and the slide D,arranged and operating as and for the purposedescribed.
